The disclosed embodiments relate to mobile computing devices. Inparticular, the disclosed embodiments relate to orientation and presencedetection for use in configuring operations of computing devices indocked environments.

BACKGROUND

The use of docking stations and other accessory devices in connectionwith mobile computing devices (e.g. smart phones, media players etc.) iswell known. Traditionally, docking stations are used to (i) recharge orsupply power to the mobile computing device, (ii) enable the computingdevice to communicate with other devices connected to the dockingstation (e.g. synchronization with a personal computer), or (iii) useadditional resources provided with the docking station (e.g. speakersfor audio output).

In a traditional scheme, docking stations and mobile computing devicesconnect using insertive male/female connectors. Numerous factors comeinto consideration when mobile devices are designed with connectors foruse with docking stations. For example, such connectors typically takeinto account the ease by which users may establish the connection (e.g.can the user simply drop the device into the cradle), as well as themechanical reliability of the connectors. When users repeatedly matedevices with docking stations, both the mating action and the removal ofthe device from the docking station can strain the connector structureand its elements.

Connectors also restrain the amount by which a device's form factor canbe reduced in thickness and/or other dimensions. Connector schemes(particularly those that abide by an industry standard) have constraintsthat dictate the physical dimensions of the male and female ends of theconnectors. As devices get smaller, accommodating the size constraintsof the connectors has become more challenging.

Overview

FIG. 1 is a representative diagram illustrating two computing devicesthat can be brought into contact for purpose of enabling one device toprovide a power and/or data signal to the other device, according to anembodiment of the invention. Numerous embodiments described herein,including an embodiment such as described with FIG. 1, reference a MCDand dock as two devices that are brought into contact with one anotherfor purpose of power/data transfer without use of traditional insertiveor mechanically coupled connectors. However, different kinds of devices(e.g. portable devices and accessory devices) may be used withembodiments described herein. In the examples provided for the numerousembodiments described, the two devices may correspond to, for example, aMCD and an accessory device for the MCD. In one implementation, the MCDis a multi-purpose device having cellular data and telephoniccapabilities, while the accessory device corresponds to, for example, adocking station (for communications and power supply), sticky (orpiggy)-back accessory, a light projector, a speaker set, or headsetstation. As an addition or alternative to cellular telephony/datacapabilities, the MCD may include, for example, functionality for use asa media player, a camera or video recorder, a global positioning unit,an ultramobile personal computer, a laptop computer, or a multi-purposecomputing device. Numerous other examples and implementations aredescribed herein, including embodiments in which three or more devicesare interconnected through one or more connector-less connections.

Accordingly, a system 100 includes a MCD 110 that is supported orotherwise retained by a dock 120. The manner in which the MCD 110 issupported may vary. Moreover, as described with one or more embodiments,the orientation of the MCD on the dock may be changed by the user forpurpose of configuring operations or behavior of one or both devices.According to an orientation of an embodiment shown, the MCD 110 issupported on the dock 120 in a partially upright position along itslength axis (L). Such an orientation may correspond to a ‘portrait’position. In an embodiment in which alternative orientations arepossible, the ‘landscape’ positions, or positions in between theportrait and landscape positions may be possible.

According to an embodiment, the dock 120 utilizes physical supportstructures (not shown), such as shelves, platforms, hooks or mechanicalretention features, to retain the MCD 110 in a docked or mated position.In another embodiment, magnetic clasps may be included or provided thedock 120 and/or the MCD 110 to secure retention of the MCD against thedock.

The dock 120 may include resources 121 for generating or extending powerand/or data signals to the MCD 110. For example, the dock 120 may bemated with a power outlet 124 or another computer 126 (e.g. desktopcomputer) to extend power and/or data signals. The resources 121 mayinclude circuitry or hardware, such as AC/DC converters and regulators.In order to enable the dock 120 to receive electrical power from apersonal computer or other computing station, one implementationprovides for the dock 120 to include a physical connector port, such asprovided by a Universal Serial Bus (USB) connector. Additionally, thedock 120 may include data acquisition capabilities, provided throughconnector ports with the computer 126, wireless ports (e.g. cellular,WiMax connection, Bluetooth), Internet ports, and media feeds (e.g.provided through television tuner and cable).

As shown by an embodiment of FIG. 1, the MCD 110 has a housing shell 112having a thickness (t). The housing shell 112 may be used to retaininternal components of the MCD 110, such as a circuit board, processor,memory, or components of a display assembly. The MCD 110 may bestructured so that a primary facade 115 (e.g. the back panel) of thehousing shell 112 rests on a receiving surface 125 of the dock 120.

According to embodiment, the MCD 110 and dock 120 are electrically matedwithout use of connector structures. In one embodiment, one or moresignal paths 132 is defined by conductive or current-carrying elementsthat are distributed in the dock 120 and the MCD 110. The signal path(s)132 is continuously conductive in carrying one or more signals (e.g.power and/or data) between the dock 120 and the MCD 110. In anembodiment in which signal path(s) carry power, the signal may extendthrough the housing shell 112 (and its thickness) and from/to arecharging module 118 or circuit of the MCD 110. Such a power signal maybe delivered from the dock 120 to the MCD 100 for the primary purpose ofrecharging a battery module 119 on the MCD. In other implementation,such as when the other device is another type of accessory (and not adock), the power signal may be delivered from the MCD 110 outward.

In an embodiment in which the signal path(s) 132 carry data, the signalmay be delivered or exchanged between data handling resources of eachdevice. The MCD 110 may be equipped with data receiving elements 113 (oralternatively, a communication port) provided inside or with thethickness of the housing 112. In the MCD 110, the processor (not shown)may interconnect to the data receiving elements 113 or communicationport provided interior to the housing 112 to process and use the datasignal. Still further, the data signal may be delivered outward from theMCD 110 to the accessory device (which does not necessarily have to bethe dock) in a similar manner. Various types of data handling resourcesmay be provided on the dock 120 in order to communicate data out orreceive data in. Such components may include a processor, storageresource, or physical/logical communication port to another device ormedium. For example, the dock 120 may enable synchronization of datafiles and/or records between a third computer (e.g. personal computer126) and the MCD 110.

As an alternative to a continuously conductive signal path, anotherembodiment provides that the signal path 132 that is enabled from theconstruction of the MCD 110 and dock 120 is inductive or transductive.In particular, the signal path 132 may use induction or othertransduction to convey signal energy from or between respective signalpoints of the dock 120 and the MCD 110. Thus, the non-continuously (ortransductive) signal path may be used to carry power and/or data, toand/or from the MCD 110 or dock 120.

Continuously Conductive Signal Path

FIG. 2A is a representative block diagram of a computer systemcomprising the MCD 110 and dock 120, each of which is configured tocommunicate signals on a continuously conductive signal path, under anembodiment. The MCD 110 and dock 120 may be mated and retained in amanner described with an embodiment of FIG. 1. An exterior surface 212,222 of MCD 110 and dock 120 respectively may be in contact as a resultof the retention of the MCD on a receiving surface of the dock. Theexterior surface 212 of MCD 110 may correspond to, or be provided by,the exterior facade of the housing shell 112 (FIG. 1). A signal source225 on the dock 120 (e.g. such as a power inlet 124 in combination withresources 121) may generate a signal (e.g. power) that is conveyedthrough conductive elements 224 provided on the exterior (or receiving)surface 222 of the dock. Likewise, the exterior surface 212 of the MCD110 includes conductive elements 214 that extend through the thicknessof the housing shell and onto a charging circuit or module 230.

In an embodiment, the design of the dock 120 and/or how it receives MCD110 may be configured to provide active or inherent retention featuresthat force contact between conductive elements 214 and 224 on respectiveexterior surfaces 212, 222 of the dock 120 and the MCD 110 (at leastwhen properly positioned). Such retention features may correspond tomagnetic clasps, or to mechanical features such as platforms, ledges orsurface features. Alternatively, coupling features, such as biasedinsertion members (e.g. on the dock 120) and receiving holes (e.g. onthe MCD 110) may also be used. In another variation, the dock 120 may beconstructed to receive the MCD 110 in a manner that orients the MCD 110so that gravity forces its exterior surface 212 down into contact withthe receiving surface 222 of the dock. Optionally, the retentionfeatures enable the user to select and to change an orientation of theMCD 110 when retained on the dock 120.

In an embodiment, the signal exchanged via the continuously conductivesignal path is for power. Accordingly, one implementation provides thatthe dock 120 connects to a power source 252 (e.g. inlet 124, personalcomputer 126) and becomes a source of power for the MCD 110. The powersignal path initiated by the dock 120 may be in the form of a closedcircuit, requiring positive and negative polarity connection points withthe MCD 110. Thus, two separate pairs of conductive elements 214, 224(or set pairs) may be provided for purpose of conveying power, with eachpair of conductive elements 214, 224 providing a polarity in theconnection. In the case of an independent data signal path, one or morecontact points may be used to carry one or more signals. For example,two or three signals may be conveyed between the devices. As alsodescribed elsewhere, some embodiments also provide for an integratedpower and data signal, so that power and data are carried on one pathand at the same time.

FIG. 2B is a representation of one or more continuously conductivesignal path 250, as extended from or between the dock 120 to the MCD110, using conductive elements provided on both devices (such asdescribed with previous embodiments). The signal paths 250 may carrypower and/or information from the dock 120 to the MCD 110, oralternatively, from the computing device to the station. On the dock120, the signal paths 250, when provided in the form of power, may begenerated from electrical power source 252 and signaled out usingconductive elements. In one embodiment, the circuit elements providedfrom the dock 120 include wiring or circuit elements that terminate asconductive elements 224 on the exterior surface 222. The conductiveelements 224 may correspond to, for example, metallic elements thatterminate electrical leads from a power source of the dock 120.

The continuously conductive signal path 250 may extend to the conductiveelements 215 on the exterior surface 212 of the MCD 110, which act asterminals for receiving the power signal from the dock. The conductiveelements 214 of the MCD 110 may extend through the thickness of thehousing shell 112 to the charging circuit or module (or alternatively,some other signal handling component). The conductive elements 214 onthe exterior surface 212 (FIG. 2A) may thus form positive and negativeterminals for receiving corresponding connections with conductiveelements of the dock 120.

MCD Construction for Enabling Conductive Signal Path

FIG. 3A illustrates a MCD configured to enable a conductive andconnector-less connection with an accessory device, under an embodiment.In one implementation, the MCD 300 corresponds to a cellular telephonydata device, such as a so-called “Smart phone” or “mobile companion”.Such devices use cellular networks to enable telephony operations,messaging (e.g. e-mail, instant messaging, Short Message Service (SMS),Multimedia Message Service (MMS)) and Internet browsing or other networkoperations. As an alternative or addition, such devices may enablenetwork connectivity through alternative wireless network mediums, suchas Wireless Fidelity (or ‘WiFi’) as provided under standards such asthose set forth by IEEE 802.11(b) or (g). While embodiments describedherein focus on cellular telephony data devices, other types ofcomputing devices may also be used with embodiments described herein,such as multimedia devices, ultramobile personal computers, GPS units,or cameras/video recorders.

According to an embodiment, the MCD 300 includes a housing 310 have afront facade 313 that opposes a back or rear facade 315 (FIG. 3B). Thefront facade 313 typically incorporates user-interface features, such asa display 316, buttons or touch-sensitive features 317, as well as anyone of many possible other features, such as 5-way navigation mechanisms(with four way scrolling and center select), keypads or keyboards,microphones, dials, and camera lenses and numerous other features.Conventional devices often incorporate physical connectors into aperipheral edge 309 (e.g. such as USB or micro-USB ports), for purposeof performing battery recharge or data transfer/exchange. In contrast,it is possible for embodiments described herein to include no suchphysical connector ports to perform recharge or data transfer functions.

FIG. 3B is an isometric rear view of the MCD of FIG. 3A, under anembodiment. As shown, the housing 310 may be provided as a shell thatencompasses the rear facade 315. According to an embodiment, the housing310 is structured to enable use of a continuously conductive signal paththat may be communicated from (or to) another device (e.g. dock) that isbrought into contact with the MCD. In an embodiment, housing 310 of aMCD 300 is structured to include conductive elements 302 that connectwith designed conductive elements 412 (e.g. see FIG. 6A) of a dock 400(FIG. 6A). The conductive elements 302 extend a thickness into the shellof the housing 310 and electrically connect to a recharging circuit orpower module (not shown in FIG. 3) of the MCD 110. Such a configurationenables the MCD 300 to be connector-less, in that the device requires noconventional connectors, such as those that require a physical interfaceon the exterior of the housing. The connector-less features enable theexchange of signal paths for both power and data, without requiring, forexample, connector physical layers, apertures to receive insertiveelements from the connecting device, or conductive extension elements.Rather, strategically positioned conductive elements 302 may be providedon a facade 315 of the housing 310. Moreover, these conductive elementsmay be incorporated into a mid-region 308 of the facade 315, or at leastapart from the edges 311 or facade boundaries of the housing 310, whereconventional connector elements are provided.

In an embodiment of FIG. 3A and FIG. 3B, the conductive elements 302 areintegrated to appear as aesthetic or design elements. In one embodiment,the conductive elements 302 are integrated into a logo 304 that appearson the back facade 315. For example, one letter of a logo may provide apositive terminal for receiving a power signal, while another letter ofa logo may provide a negative terminal. The combination of positive andnegative terminals may create a power signal that extends from the dock120 (see FIG. 1) to the MCD 300.

As an addition or alternative, one or more embodiments provide thatadditional conductive elements may be used to carry data andinformation. For example, another of the letters in the logo maycorrespond to a logo that is positioned to receive or provide a datasignal.

FIG. 4 is a side cross-sectional view of the housing 310 of the MCD 300,under an embodiment. In one implementation, the housing 310 may beprovided by an upper shell 362 and a lower shell 364. The upper shell362 may provide the front facade 313, while the lower shell provides theread facade 315. During assembly, the shells 362, 364 may be sealed tocomplete the housing 310. The housing 310 may be characterized by athickness t. Additionally, the housing 310 may be structured to assumeany one of a pre-designed form factor, with contours or designparameters that meet design parameters. The conductive elements 312 maybe inserted into openings 323 or otherwise integrated into the facade315 so as to provide conductive surface points 325 in a mid-portion ofthe facade 315. The conductive surface points 325 may correspond tobumps or other surface features, or alternatively be smooth from atactile perspective. A conductive medium 332 (e.g. plate, cable, leadlines) may extend inside along an inner surface 316 of facade andterminate at a battery module 370 or component.

In one variation, the conductive medium 332 is provided in a region ofthe lower shell that corresponds to a battery cover. Optionally, thetermination may be provided by connector elements, such as pogo pintermination points 335. The pogo pin termination points 335 may mate orconnect with corresponding receiving elements of the battery module 370of the MCD 300 when the battery cover is closed, or when pressure isapplied to the battery cover (such as when the back façade 315 is restedon the receiving surface of the dock). In such an implementation, apower circuit for carrying a power signal from the dock 120 (FIG. 1) tothe MCD is created and effective under conditions of (i) receiving apower signal, and (ii) having the battery cover pressed on the dockingstation.

FIG. 5 is an isometric interior view of the lower shell 364 (or portionthereof, such as the battery cover) which provides at least a portion ofthe exterior rear facade 315 (FIG. 3B), according to an embodiment. Asshown by an embodiment, conductive plates or leads 332 may extend fromselected logo elements 304 which are integrated or otherwise formed onthe exterior of the lower shell 364. The leads 332 may extend to a pointcoinciding with positioning of the battery module 370 (FIG. 4) so that aresulting power signal carried between the dock 120 (see FIG. 1) and theMCD 300 (see FIG. 1) may recharge the battery element of the device. Inthis way, the conductive surface points 325 (e.g. see FIG. 4) may appearas elements of a logo on the rear facade (e.g. see FIG. 4). Toaccommodate a power signal, an embodiment assigns one logo element 304to act as a positive terminal and another logo element 304 to act as anegative terminal. In this way, a power circuit may be created andshared between the MCD 300 and the dock (or other device) for purpose ofrecharging the batter module 370 on the MCD.

As an alternative, the same construction may be used to enable reversalof the power signal out of the device. In one implementation, the powersignal may use the battery module 370 of the MCD as the source in orderto signal out the power and/or charge to an accessory device in contactwith the rear facade 315.

Dock for Enabling Conductive Signal Path

According to an embodiment, a dock may be structured to provideconductive elements that are selectively positioned or formed to matewith corresponding conductive elements of the MCD 300 (see FIG. 3). Adock for supporting the MCD in a manner as described may have any ofmany possible form factors. The dock may extend an arrangement ofcontact elements that are aligned to make contact surface points 325 onthe rear facade 315 of the MCD 300 (FIG. 3B).

FIG. 6A is an isometric view of a dock for use in mating with a MCD suchas shown and described other embodiments. In an embodiment, dock 400includes a body 405 which extends a height from a support surface (e.g.ground or table-top) and enables support of the MCD 300 (FIG. 3B) in anupright or partial upright position. In an embodiment, the dock 400includes a receiving surface 410 which supports the MCD on its backfacade 315, so that the device can be viewed face-up when retained onthe body 405.

As shown by an embodiment of FIG. 6A, the body 405 vertically slants thereceiving surface 410 on which the MCD 300 (shown in FIG. 3B) may restand/or be held in position. To prevent the MCD 300 (FIG. 3B) formsliding off, one embodiment provides that magnetic retention featuresmay be incorporated into the receiving surface 410 and/or device housing310 (FIG. 3B). As an alternative or addition, a shelf may be positionedat the gravitation bottom of the slanted surface. Other mechanical ormagnetic retention mechanisms may alternatively be employed. Forexample, as another alternative or addition, the receiving surface 410may be horizontal or provided with other retention mechanisms to holdthe device in place when it is rested on the receiving surface. Thus,while some embodiments recited contemplate a passive ‘mating’relationship between the computing device 300 and the dock 400 (e.g.gravitational), retention features (such as magnetic clasps) may providefor active retention of the MCD on the receiving surface 410.

In order to enable the continuously conductive signal path from the dock400 to the MCD 300, embodiments include different patterns orarrangements for the manner in which conductive elements 422 on thereceiving surface 410 of the dock are provided. According to oneembodiment, the conductive elements 422 of the dock 400 are provided ina circular and concentric arrangement, although alternative arrangementsmay be employed. In a concentric ring arrangement, an outer ring 431 mayprovide one terminal for a power signal, while an inner ring 433 mayprovide the opposite pole. Each ring 431, 433 may be spaced from oneanother so that when the MCD is positioned on the receiving surface 410,the conductive elements on 315 the façade of the MCD 300 (see FIG. 3B)will contact the correct ring, regardless of whether the MCD is in theportrait or landscape (or in between) orientation when retained on thereceiving surface.

As a variation or extension to such an embodiment, the device may haveanyone of a plurality of positions on the receiving surface 410. Thepositions may be discretely defined positions (e.g. north, south, eastor west) or continuous on a ring or arc.

According to an embodiment, the receiving surface 410 is magnetized. Inone embodiment, the use of magnetic forces may be accomplished byintegrating one or more magnetic elements into the body 405, so that themagnetic field emits outward from the receiving surface. The magneticfields may attract to elements on the MCD 300, such as the conductiveelements 302 or conductive plate 332 of the MCD.

FIG. 6B and FIG. 6C show the MCD 300 surface mounted to the dock 400. Asshown, the MCD 300 may be surface mounted in either portrait (FIG. 6B)or landscape (FIG. 6C) orientations. More orientations are possible,depending on the manner in which the MCD 300 is retained. In anembodiment in which magnetic forces are used, the magnetic forces enablethe MCD 300 to be positionable on the receiving surface 410 in adiscrete number of positions. For example, the magnetic forces may beconfigured to enable the MCD 300 to occupy portrait or landscapepositions, as shown by FIG. 6A or FIG. 6B. Alternatively, one of fourpossible positions may be possible, including opposite portrait andlandscape orientations (i.e. north, south, east and west). When specificpositions are enabled with magnetic forces, positions in between thosespecified positions may be repelled. Thus, magnetic forces may be usedto create a defined number of possible orientations by which the MCD 300may be oriented with respect to dock 400.

As another variation, the dock 400 may be configured to enable the MCDto have any one of a plurality of positions defined anywhere along anarc. For example, as described with an embodiment of FIG. 3B, the device300 may include a ring of ferrous material that enables it to occupypositions on an arc, rather than be repelled from defined orientations.Numerous further variations are possible and some are described ingreater detail below.

The use of magnetic forces may enhance the conductive connection betweenthe surfaces of the MCD 300 and dock 400. Still further, as analternative or addition to embodiments such as described above, anotherembodiment may surface treat conductive elements 612 or other portionsof the façade of the MCD.

FIG. 6D illustrates an alternative configuration for a back façade ofMCD, under an embodiment. In an embodiment of FIG. 6D, an arrangement ofelectrical contacts 680 is shown to form a logo 682 for the back façade315 of the MCD. The logo 682 may comprise multiple letters, each ofwhich is termed a logo element 681. In one embodiment, each logo elementmay comprise of multiple pins, or pogo pins that form an electricalconnection. Such a formation of electrical contacts or pins is referredto as a “Bed of Nails” configuration. In one embodiment, each logoelement 681 carries a signal path. In the example shown, the logoelements 681 combine to include a positive and ground signal and twodata signals (+ and −). Individual elements (i.e. logo elements 681) mayhave varying pin dimensions. For example, a logo element may include oneor two pins provided on length portions of the element. Various otherpin configurations are contemplated.

In one implementation, at least some of the electrical contacts 680 arepogo-pins that insert inward to a conductive element (not shown) that iscommon to all the pogo-pins in that logo element 681. When the rearfaçade 315 is surface mounted to the dock, at least some electricalcontacts 680 of individual logo elements 681 move inward to form aconductive connection with corresponding electrical elements on thedock. This configuration for the back façade may enhance the conductiveelectrical connection where the contacts 680 meet the correspondingelements on the receiving surface of the dock.

Numerous other enhancements and features may be combined with electricalcontacts formed on the rear façade 315 of the MCD 300. As anotherexample of a feature or enhancement, the electrical contacts on both therear façade 315 and the dock may be surface treated to be rough in orderto facilitate retention of the MCD in the docked position.

While FIG. 6D illustrates use of logo elements, other elements on therear façade 315 may be used. For example, the pogo elements that providethe conductive surfaces may be provided in various geometric shapes(e.g. circles) or blended by color or appearance with the housing of theMCD.

FIG. 7A through FIG. 7C illustrate an alternative design for the dockand MCD, under another embodiment. In FIG. 7A, the dock 500 includes anelevated platform 708 that serves as a support structure for the MCD300. A contact surface 710 on which the conductive elements is providedmay extend vertically from the platform 708. A pair of contact elements702 representing positive and negative contact points for an emittedpower signal may be provided on the contact surface 710.

FIG. 7B illustrates the MCD 300 surface mounted on the dock 500 in aportrait mode. The platform 708 may support the MCD 300 in the uprightposition. As shown by FIG. 7C, the MCD 300 may be moved into a landscapeposition and supported by the support structure 708. In an embodiment,the contact elements 702 may remain in contact with the contact surfacepoints 325 (FIG. 3B) on the rear facade 315 (FIG. 3B) of the MCD 300when the MCD has either the landscape or portrait positions on the dock.

Power/Data Conveyance in Conductive Signal Path

In an embodiment, a continuously conductive signal path such asdescribed with FIG. 2A and FIG. 2B may be used to convey power and/ordata. FIG. 8A represents a continuously conductive signal path used toconvey only power from one device to another. In particular, anembodiment provides that the continuously conductive signal paths conveypower from a dock 400 (FIG. 6A) to a MCD 300 (FIG. 3A). In order toconvey power with conduction, one or more embodiments provide that thecontinuously conductive signal paths include positive and negative powersignal path portions 702, 704. Thus, with reference to other embodimentsdescribed above, power may be conveyed through electrical contactbetween two conductive elements on each of the dock 400 and the MCD 300.For example, with reference to FIG. 3A, in the case where two logoelements on a rear facade 315 of the housing 310 are used to provideelectrical elements, one logo element may represent the positiveterminal and another logo element may represent a negative terminal.

FIG. 8B and FIG. 8C each illustrate an embodiment in which both data andpower are conveyed on a common continuously conductive signal path. Inparticular, an embodiment provides for modulating a power signal 712 ina manner that enables the power signal to convey information. Thus,under one embodiment, the dock 400 may convey information to the MCD 300using the same electrical contacts and signal that conveys power foroperating components and/or recharging the device's battery. FIG. 8B andFIG. 8C illustrates different types of modulation of signals that carrypower. These types of modulations include (i) pulse-length modulation,where the positive power signals 712 is pulsed and modulated in lengthof time (see FIG. 8B), (ii) frequency modulation of the positive powersignal 722 (see FIG. 8C), and/or (iii) ‘AM OOK” modulation, where thevoltage levels of the power signal are varied. According to anembodiment, the data that is conveyed through the power signals islimited in quantity, as use of power signals to convey data has inherentlimitations (e.g. noise, speed). In an embodiment, the type ofinformation that is conveyed is data for establishing subsequent localwireless communications.

In particular, one embodiment provides that the power signal is used toinitially pass credential or pairing information between devices. Suchinformation may correspond to password, device identifiers, and otherinformation that users often manually enter in order to enable, forexample, BLUETOOTH pairing. However, an embodiment such as describedrecognizes that the power signal conveyance means that two devices areplaced in contact with one another by the user. The placement of the twodevices in physical contact by the user may be viewed as aself-authenticating event. The event enables the assumption that thepassing of credential information between the two devices is authorizedor desired by the user. In one embodiment, the conveyance of the powersignal coincides with automatic transmission of credential information.For example, the dock 400 (FIG. 6A) may convey the credentialinformation for enabling BLUETOOTH (or other standardized local wirelesscommunications) to the MCD 300 (or vice-versa) (FIG. 3A). In turn, theMCD 300 may use such credential information to establish a wirelesspairing with the dock 400 (such as for BLUETOOTH or WIRELESS USB).Subsequently, other data and information, such as data corresponding torecords or media, may be passed from the MCD to the dock 400 (or thereverse).

Inductive Signal Path

While some embodiments described above provide for a conductive signalpath between a mobile computing device and a docking station, one ormore embodiments provide a non-continuously conductive or transductivesignal path to be used to carry power and/or information between thedock and the MCD. A non-continuously conductive signal path may refer tothe ability of a signal to be carried from or between devices, where thesignal undergoes transformation from current/voltage form to some otherform and back again to current/voltage. One embodiment provide for asignal path that includes an inductive segment to convey one or moresignals between the MCD and the dock.

With reference to FIG. 9A and FIG. 9B, an embodiment is illustrated inwhich the signal generated from either the dock 400 or MCD undergoestransformation from a current/voltage form into an inductive or magneticenergy form, and then back into a current/voltage form.

FIG. 9A is a simplified block diagram of a MCD 810 and dock 820, whereone or both devices are configured to communicate signals on a signalpath that has an inductive signal path portion, so as to form apartially inductive signal path 832. According to an embodiment, the MCD810 may be placed in contact with the dock 820, such as in a mannerdescribed with other embodiments (such as described with FIG. 1). Theresult is that a device exterior 808 (e.g. rear facade) comes intocontact with a receiving surface 828 of the dock. Alternatively, the twodevices may be brought into close proximity, but not necessarily incontact, in order for inductive signal communication to take place.While exterior surfaces 808, 818 of MCD 810 and dock 820 respectivelymay be in contact as a result of the retention of the MCD by the dock,the contact is not made to conductively transfer signals between thedevices. Rather, a signal source 824 on the dock 820 (e.g. such as apower inlet) may generate a signal 828 (e.g. power) that is transformedthrough a magnetic coil 826 or other inductive mechanism into a magneticfield. A corresponding coil 814 or inductive receiving component may beprovided on the MCD 810 to transform the signal 828 into an electricalsignal 816. The electrical signal 816 may be treated by various circuitelements and components in order to power components of the MCD 810,and/or to charge a battery module 819 of the device 810.

FIG. 9B illustrates an inductive signal path 850, as extended from orbetween the dock 820 to the MCD 810, using a combination ofmagnetic/inductive and conductive elements provided on both devices. Onthe dock, the signal path 850 includes a current phase 852 and aninductive (or magnetic field) phase 854. The inductive phase 854 carriesthe signal across boundaries of respective housings using magneticfield. Thus, on the device 810, the signal path 850 includes aninductive phase 854, followed by a current phase 856. The reverse pathmay also be possible, such as in the case when the MCD supplies powerand/or data to the docking station or another accessory device.

Inductive Coil Arrangements

The inductive conveyance of power and/or data signals may be achievedthrough use of coils, provided on each device that is to be coupled totransmit or receive such signals. Various coil configurations arepossible to enable conveyance of power and/or data, eitherunidirectionally or bi-directionally.

FIG. 10A through FIG. 10C illustrate different coil distributionimplementations for inductive signal conveyance, under differentembodiments or variations. In particular, FIG. 10A illustrates acomputer system that includes two coils, one on each device. The twocoils 902, 904 may be used to convey power and/or data in one signal 901that is exchanged between the two devices. Moreover, the conveyance ofeither power or data may be bi-directional.

FIG. 10B illustrates a three-coil implementation, where one of the twodevices (e.g. the dock 820) includes two coils 912, 914, and the otherdevice (e.g. MCD 810) includes just one coil 916. Such an embodiment mayprovide the advantage of lessening the weight or size required from theMCD, while enabling separate data and power exchange. In one embodiment,the coil 916 of the MCD 810 receives power 911 from one coil 912 on thedock, and data 913 from the other coil 914. Optionally, either the power911 or the data 913 signals may be bi-directional, meaning the coil 916on the MCD 810 may communicate the signals back to the dock 820. In oneimplementation, the coil on the MCD 810 signals data to the independentdata coil on the dock 820.

FIG. 10C illustrates another implementation in which each of the dock820 and MCD 810 include two coils. In particular, power and data coils922, 924 on the dock 820 may communicate power 921 and data 923 signalsto respective coils 932, 934 on the MCD 810. In an embodiment, the powerand data communications are bi-directional.

Computer System Using Inductive Signal Path

FIG. 11A illustrates a simplified block diagram of a computing systemthat provides for inductive conveyance of power and/or data signals,under an embodiment. The computing system 1000 includes MCD 1010 anddock 1020 (which may be equivalent to those devices shown in FIG. 3A andFIG. 6A respectively, or other embodiments described herein whichprovide for inductive signal transmission). In an embodiment, the dock1020 includes a central processor 1022, a power subsystem 1024 and acommunication subsystem 1026. The MCD 1010 includes a power subsystem1012, a signal processor 1014, and a communication subsystem 1016.Additionally, the MCD 1010 (and optionally the dock 1020) includenumerous other components, such as a central processor and memoryresources for enabling application executions, cellular and datacommunications, and numerous other functions that are part of the usageof the MCD 1010.

On the dock 1020, the power subsystem 1022 includes a connection to acontinuous power supply 1021, such as a wall outlet. Additionally, thepower subsystem 1022 includes components for converting and regulatingthe signals from the power supply into a form that is suitable forconveyance using, for example, an inductive medium. Additionally, thepower subsystem 1022 includes one or more coils for converting anelectrical signal originating from the power supply 1021 into aninductive signal. The communication subsystem 1026 may include wirelessor wireline port(s) to receive and send data to other devices, includingwith other computers or data sources (e.g. media feeds from otherdevices, such as set-top boxes) or media output devices. In anembodiment, the communication subsystem 1026 also enables inductive datahandling from data communicated by one of the inductive signal pathsthat extend between the two devices. As mentioned, such data may beconveyed by either modulating an inductive power signal or using aseparate data signal path.

The central processor 1024 of the dock 1020 may be configured to handleincoming data signals from the communication subsystem 1026, whetherfrom the other resource or from the MCD 1010. Additionally, the centralprocessor 1204 may control data that is communicated out, either to theother resource or to the MCD 1010 (using the inductive signal path).

On the MCD 1010, an embodiment provides that the power subsystem 1012receives an incoming power signal 1008 from the dock 1020 anddistributes the power signal in modified or regulated form to eitherother components or to the battery for recharge. In one implementation,the power signal 1008 is signaled through an inductive path from thedock 1020 to the MCD 1010, in a unidirectional fashion. Thecommunication subsystem 1016 is configured to communicate with the dock1020 to receive and/or transmit data 1009. One embodiment provides thatthe communication subsystem 1016 may include resources to demodulatedata carried on the power signal. In particular, the communicationsubsystem 1016 may use its resources to implement a protocol forretrieving and using credential information (e.g. preliminary data forestablishing subsequent wireless communications) from characteristics ofmodulations in the power signal 1008. The protocol may further providefor the communication subsystem 1016 to switch to, for example, astandardized wireless communication medium (e.g. BLUETOOTH) using thecredential information and/or other data communicated by the powersignal 1008. Still further, another embodiment may provide for thecommunication subsystem 1016 to be enabled to generate modulated poweror other signals to communicate to the dock 1020 or other device. Forexample, as shown by an embodiment of FIG. 10B, two coils may be used onthe dock, including one coil that communicates both power and data andanother that receives data from the MCD 1010. The communicationsubsystem 1016 may perform functions of both retrieving data from themodulated data signal and communicating data out to the data receivingcoil on the MCD 1010.

In one embodiment, data may also be combined with the power signal 1009by modulating the power signal. In one implementation, the dock 1020signals data with the power signal 1009 as a preliminary step toestablishing a different wireless communication relationship. In anotherembodiment, the data signal 1008 may be communicated to or from the MCDseparate from the power signal.

While numerous embodiments described above provide for computer systemsthat utilize inductive signal paths, other embodiments provide for otherkinds of transductive signal paths. Such alternative transductive signalpaths may use alternative signal carrier mediums. In particular, atransductive signal path may be formed by alternative mediums that carrypower and/or data. Such other mediums correspond to (i) a light mediumfor carrying a portion of a power or data signal as light, (ii) anacoustic medium for carrying the signals as through acoustics.

Dock Enhancements

FIG. 11B illustrates an alternative configuration for a dock, asconfigured with any of the embodiments described above. In anembodiment, a dock 1120 may be configured to enable transmission ofcontinuously conductive and/or transductive power or data signals to theMCD. In addition, the dock 1120 is configured to include a receivingstructure 1130 for an alternative device that can be used with the dockand/or the MCD. In one embodiment, the receiving structure 1130corresponds to a slot for receiving a headset 1140, such as a BLUETOOTHenabled headset for enabling hands-free telephony.

Data Pairing and Combined Functionality Applications

Some embodiments recognize that an appropriately configured MCD may beintermittently or selectively paired with the dock in order to enhancethe functionality provided through one or both devices. In anembodiment, the operability of the MCD, or applications that execute onthe MCD, may be altered when the device is placed in contact with thedock. In another embodiment, some data may be exchanged through thephysical contact of the MCD being placed in contact with the dock. Thisdata exchange may enable, facilitate or enhance local wirelesscommunication (or other communication mode) between the two devices.Still further, as an alternative or addition to embodiments described,the orientation of the MCD on the dock may be detectable, and used toenable or configure operations on one or both devices.

FIG. 12 describes a method for configuring operations of the MCD when itis placed in contact with the dock, according to an embodiment. A methodsuch as described may be performed in whole or in part on a MCD such asdescribed with any of the embodiments provided above. However, indescribing an embodiment of FIG. 12, reference is made to elements shownwith an embodiment of FIG. 11A, and such reference is intended to beillustrative of components that are suitable for performing a step orsub-step being described.

In step 1210, one device performs presence detection as to whether thetwo devices are placed in position to be docked. In the docked position,the MCD 1010 may receive a power signal from the dock 1020. In oneimplementation, such presence detection corresponds to either of the twodevices being placed in contact with one another, so as to enable aninductive or conductive signal path (depending on the embodimentimplemented) for the power signal. In an embodiment in which aninductive signal path is used, docking may be accomplished by twodevices being brought in close proximity. As such, in some embodimentsin which inductive signal paths are utilized, physical contact is not arequirement for presence detection. One or both devices may beconfigured to detect a signal resulting from, for example, the MCD 1010being rested on the dock 1020 in an orientation described with any ofthe other embodiments.

While embodiments provide that either device can perform presencedetection, one embodiment provides that the MCD 1010 performs theinitial detection and responds accordingly. The response may includecommunicating back to the dock 1020 that the two devices are docked.When the two devices are docked, either of the power or data signals maybe received through use of a connector-less medium. Alternatively,sensors or other elements (magnets) signal separately the presence ofthe other device when the two devices are brought into contact. Oncepresence of the two devices being in the docked position is detected,removal of the MCD 1010 from the docked position may also be detected.In one implementation, removal of the MCD 1010 from the dock 1020 may bedetected by detecting a break in the incoming power signal.

In step 1220, the MCD 1010 configures its operations in a manner thatrecognizes the presence of the dock (i.e. ‘docking’ behavior). The MCD1010 may configure itself in a variety of ways. For example, similar tomany conventional approaches, the device may suspend power-savingfeatures or automatically perform data synchronization operations. As anaddition or alternative to such configuration steps, the MCD 1010 mayperform one or more sub-steps 1222, 1224 and/or 1226, as described belowand elsewhere.

In an embodiment, sub-step 1222 provides for performance ofpresence-centric functions and operations that utilize or combine thefunctionality, capabilities or access rights of the dock 1020. In oneimplementation, presence-centric functions and operations enable the MCD1010 to prioritize settings or modes of use based on detecting presenceof the dock 1020. Additionally, one or more embodiments provide that theMCD 1010 performs functions and operations (including mode settings)based on detecting removal of the MCD 1010 from being in contact withthe dock 1020. Still further, the dock 1020 may provide access to otherresources (e.g. other computers, media devices etc.) and the act of theMCD 1010 docking with it serves as authorization for the MCD to accessor use the extended resources provided by the dock 1020. The followingusage scenarios provide examples of how sub-step 1222 may beimplemented.

Call Handling: Absent being docked, the MCD 1010 may be configured toenable telephony operations, including enabling the user to answerincoming calls through manipulation of anyone of multiple possibleuser-interface features present on the MCD. When docked, however, theMCD 1010 may implement a mode that makes specific programmaticallyimplemented assumptions about call handling. These include any one ormore of the following: (i) if an incoming call is received while the MCD1010 is in the docked position, and the user lifts the device off thedock 1020, then the call should be automatically answered; (ii) if theuser places the MCD 1010 on the dock 1020 after receiving an incomingcall, the MCD either terminates the call or places the call on speakerphone; and/or (iii) if the user answers the call when the MCD 1010 isdocked, the MCD 1010 places the call on speaker-phone.

An embodiment such as described above may be extended to accessorydevices. For example, as described with an embodiment of FIG. 11B, aheadset may be coupled with the dock 1020 to receive a power signal.Either the MCD 1010 or the dock 1020 may be configured to detect (i)presence of the headset, and/or (ii) removal of the headset from thedocked position. Such presence detection may be performed by detectingvariation or change to the power signal, or by having the headset signalthe MCD 1010 (or dock 1020) when it stops receiving power from the dock(signifying it has been removed from its docked position). When anincoming call is received, and the headset is removed, logic on the MCD1010 may be configured to answer the incoming call using the headset.

Data Synchronization/Exchange: When presence of the MCD 1010 in thedocked position is detected, one or both devices may initiate dataexchange or synchronization functions. For example, the MCD 1010 mayinitiate synchronization operations between itself and whatever computeris connected to the dock 1020. The synchronization operations may seekto reconcile or synchronize records on the MCD 1010 with those on theconnected personal computer (or alternatively the dock 1020).

In one embodiment, the mode of communication is at least partiallywireless. For example, a local wireless communication medium (such asprovided by BLUETOOTH 2.0 or WIRELESS USB) may be used to perform thedata exchange between the MCD 1010 and the dock 1020. The dock 1020 mayserve as an intermediary or pass-through for the personal computer, soas to acquire and pass data to and from the MCD 1010 on behalf of thepersonal computer. Alternatively, the MCD 1010 may communicate directlywith the personal computer.

In another embodiment, communication mediums other than local wirelesscommunications (such as BLUETOOTH) may be used. For example, data to andfrom the MCD 1010 may be exchanged over an inductive channel link, whichmay be integrated or provided with an inductive power signal (e.g. seeembodiments of FIG. 6A). In such an embodiment, the dock 1020 acts as ahub for a locally attached personal computer. The dock 1020 is then ableto negotiate or otherwise provide data flow with the MCD 1010 over theinductive channel.

Other communication mediums may also be used. As an alternative, the MCD1010 and the dock 1020 may communicate and exchange data using aninfrared (IR) communication medium. In one implementation, the dock 1020converts the IR communications from the MCD 1010 into, for example, USBtype local data transfer protocols.

Media Playback: When the two devices are detected as being docked, oneor both devices may assume operations or a role for the media playback.For example, the user may initiate media playback on the MCD 1010, andthe device will then seek to use audio output resources provided on orwith (e.g. connected to) the dock 1020. The MCD 1010 may use its owndisplay for graphic or video output when outputting the audio. If mediaplayback is initiated and the two devices are separated, media playbackmay be terminated. In one implementation, separation may be detectedwhen one or both devices detect termination of the power signal. Forexample, the MCD 1010 may detect that it has stopped receiving power,and then it may communicate this information to the dock 1020.Alternatively, the MCD 1010 and dock 1020 may each be configured to sendconfirmation communications until the ‘power-break’ is detected, inwhich case the combined functionality (such as the media playback) isterminated.

In an embodiment, sub-step 1224 provides for paired operations orfunctionality to be performed. Paired functionality means some level ofauthentication, trust or credential exchange is initiated and completed,followed by activity on one or both devices under the assumption ofauthentication or trust.

Wireless Data Exchange: For paired operations or functionality, oneembodiment provides that the two devices perform a credential exchange,followed by performance of wireless communications, in response to theMCD 1010 being docked in a manner such as described. Additionally,typical local wireless communication protocols require some dataexchange to negotiate two devices before substantive communications isperformed. According to an embodiment, when the MCD 1010 is docked (e.g.the device receives a power signal), the device seeks to establish orcontinue the partnership for subsequent wireless communications with thedock. Thus, embodiments provide that the credential exchange isperformed in a connector-less manner, using, for example, a conductiveor inductive signal path such as described with other embodiments.Subsequent to the credential exchange, wireless communications areutilized.

As an addition or alternative, the dock and the MCD 1010 may be capableof negotiating a pairing or synchronization with another device. Inparticular, an embodiment provides that the dock (or alternatively theMCD 1010) can (i) act as a proxy or intermediary to enable the MCD 1010(or the dock) to be paired with a third device, or (ii) establish athree or multi-way relationship with another device. [0 172] Withfurther reference to an embodiment of FIG. 12, sub-step 1226 providesthat the MCD 1010 and/or dock 1020 perform orientation-dependentfunctions. In one embodiment, the dock 1020 detects the orientation ofthe MCD 1010 in the docked position and configures its operation orcommunicates the orientation information to the MCD. In anotherembodiment, the MCD 1010 detects its own orientation in how it iscoupled to the dock. Orientation may correspond to detection of: (i)whether the device is in portrait or landscape mode; (ii) whether thedevice is in one of multiple possible discrete positions (e.g. north,south, east, west); and/or (iii) the position of the MCD on a continuousarc. Numerous examples of orientation dependent functionality areprovided below, as well as elsewhere in this application. Orientationdependent functionality is also described in greater detail below.

FIG. 13 is a block diagram that illustrates different data exchangeoperation that may be performed through pairing of docked devices, inaccordance with one or more embodiments. As shown by FIG. 13, when theMCD 1010 is placed in contact to receive the power signal from the dock1020, one or both devices are triggered to initiate negotiations forenabling subsequent local wireless communications. The subsequent localwireless communications may be performed under established industryprotocol (e.g. establishment of BLUETOOTH credentials), requiringpassage of certain information or data between two devices beforecommunication may be initiated.

If, however, the two devices are unknown to each other, conventionalapproaches have required that a partnership be established for futuredata exchanges. Such partnerships typically require use of set-upoperations that require manual involvement from the user. For example,conventional BLUETOOTH pairings often require the user to operate onedevice to wirelessly seek out another, and to provide input on at leastone device so that the two devices are ‘trusted’. In contrast to suchconventional approaches, one or more embodiments provide for configuringthe MCD 1010 and/or dock 1020 so that when the two devices arephysically docked, some or all of the credential information andnegotiations that have previously required manual effort are performedautomatically, so as to eliminate or reduce user-involvement. Suchautomation in the acquaintance and/or pairing of two devices may beenabled because the assumption may be made that the user of both devicesis physically present when the two devices are docked (as he must haveplaced the two devices in physical contact or close proximity). If thetwo devices are known to each other, the negotiations may mostly requireidentification of one or both devices. However, while many conventionalapproaches require manual intervention to establish pairing using localwireless communications, an embodiment provides that one or both devicesare configured to automate at least a portion of the credentialestablishment. In particular, at least some data that is typicallyentered by the user as part of establishing the BLUETOOTH or other localwireless communication relationship may be passed through inductive orconductive signal exchange. Typically, such data is required from theuser for security reasons.

Thus, with reference to FIG. 13, when the two devices are docked, thepower signal 1342 may be detected on one or both devices. Subsequently,credential information 1344 is exchanged between the two devices 1010,1020 for use in enabling subsequent wireless communications. In anembodiment, the credential information 1344 is modulated into the powersignal. For example, in an embodiment in which the power signal isinductive, inductive modulation may be used to incorporate thecredential information 1344 into the power signal 1342. However,numerous other data communication mediums may be used to pass thecredential information 1344. These include, for example, throughradio-frequency (RF) identification, local wireless communicationprotocols (e.g. wireless USB or BLUETOOTH), though infra-redcommunications, or through acoustic coupling. In the latter case, anacoustic waveform may be modulated on the speaker-phone of the MCD 1010and received by a microphone on the dock 1020, where it can beprocessed.

In an embodiment, a data exchange 1346 may be performed between the MCD1010 and dock 1020 in response to successful use of the credentialexchange 1344. The data exchange 1346 may performed over a differentmedium than the one used to communicate the power signal 1342. Forexample, the data exchange 1346 may be communicated over a wirelesscommunication port (e.g. BLUETOOTH, Wireless USB, WiFi).

As an addition or alternative, in one embodiment, the dock 1020 may actas an interface or proxy for enabling the MCD 1010 to indirectlycommunicate with a third device or resource 1350. In such an embodiment,the dock 1020 may exchange data 1348 with the third device 1350 usinganother connection, such as a local physical connection (e.g. FIREWIRE,USB 2.0) or local wireless link. As another alternative, the MCD 1010may follow credential exchange 1344 with direct communications 1352 anddata exchange with the third computer 1350. Still further, as anotheraddition or alternative, the third computer 1350 may correspond to aresource, such as a network resource (e.g. online server or account) ormedia station.

Additionally, the credential exchange may establish the pairing to existbeyond the time the MCD 1010 is removed from the dock 1020. For example,the user may place the MCD 1010 on the dock 1020 to receive power and/orthe credential exchange. The user may then remove the device andcontinue to wirelessly communicate to or through the dock using theestablished credentials. In this way, the docking of the MCD 1010 servesas an authentication event that lasts longer than the duration of theMCD being in contact with the dock 1020.

With further reference to FIG. 13, data exchange or synchronization maybe performed between the MCD 1010 and the dock 1020, with the dockacting as an interface for a personal computer or other machine. As analternative or addition, the data exchange or synchronization may beperformed between the MCD 1010 and the dock 1020, rather than indirectlywith another computer or machines. Thus, the dock 1020 may holdinformation or records.

Still further, one or more embodiments also provide that the credentialexchange 1344 between the MCD 1010 and the dock 1020 may carry over toother uses of the MCD. Specifically, an embodiment may require the twodevices to be docked when credential exchange/pairing is established. Anassumption may be realized that the user is physically present, thus theuse of the MCD 1010 with the dock 1020 may provide a form ofself-authentication. In an embodiment, the dock 1020 may be connected orpaired with another computing device or machine. Credentials,permissions, authorizations or other pairing relationship data may betransferred from the dock 1020 to the MCD 1010. Depending on theapplication, this form of authentication may enable the MCD to (i)communicate with that other machine or computer directly, (ii) performsome operation that requires a certain permission or right, or (iii)access a guarded resource (e.g. decrypt files, provide passwordsubstitute etc.).

Still further, since the user of the MCD 1010 may be assumed to bepresent when the two devices are docked, one or more embodiments mayenable the dock to enable some form of user-access or use of anotherresource. For example, in the case where the dock 1020 is connected orpaired to a personal computer as the third computer 1350, the personalcomputer may be unlocked for a user of the MCD 1010 when the MCD isdocked to the station (or for some defined duration thereafter). Thus,the dock 1020 may receive credential information 1344 from the user andverify the identity of the user to unlock the machine. As anotherexample, the dock 1020 may be connected to a television or media outputdevice. When the user docks the MCD 1010 with the dock 1020, the dockmay communicate certain information that enables the device to full-filla role, such as operation of the television set as a remote. The rollmay be full-filled even when the MCD 1010 is subsequently de-docked fromthe station 1020. For example, the dock 1020 may be connected to thetelevision set and placed in proximity to it. At the same time, the MCD1010 may be configured to include a remote control application forcontrolling the television set. When the MCD 1010 is docked, the programis unlocked or configured to communicate with the television set, eitherdirectly or indirectly through the dock. The ability of the MCD 1010 tooperate the application and use it for the television set may remain fora duration after the MCD 1010 is removed from the dock (so that it actsas a true remote).

Orientation Functionality Anongst Docked Devices

With reference to MCD and dock in accordance with any of the embodimentsdescribed herein, an embodiment provides that the orientation in whichthe MCD is placed on the dock is selectable by the user, and that theorientation may determine or configure functionality of either device.For example, the orientation of the device when docked may be selectedby the user in order for the user to enter a form of input as to how oneor both devices (either combined or independently) behaves.

FIG. 14 illustrates a method in which an orientation of a MCD isselectable to affect operations or functionality resulting from one orboth docked devices, under an embodiment of the invention. As aprecursor, the dock and/or MCD are each physically configured to enablethe MCD to have any one of many possible positions when docked. Numerousphysical features or designs may be used to enable the device to havemore than one orientation.

FIG. 15A through FIG. 15C illustrate implementations of structuralsurface features that may be provided with the MCD and/or the dock,under different embodiments of the invention. In an implementation ofFIG. 15A, the dock 1510 may be configured to include a platform 1512 (orreceiving surface; see also embodiments of FIG. 7B or FIG. 7C) or shelfso as to receive and support the MCD 1520 in an electrically engagedmanner. The platform 1512 may be of any shape, such as elliptical orcircular, as shown in FIG. 15A. The platform 1512 may extend from a body1505 to be partially upright or vertical. One type of mechanicalfeatures to support the MCD 1520 in multiple orientations are templatestructures 1522, 1523. Template structures 1522, 1523 may be provided indifferent sets. In the implementation shown, a first set of templatestructures 1522 support the MCD 1520 in the portrait (or lengthwise)docked orientation, while the second set of template structures 1523support the MCD 1520 in the landscape (or widthwise) docked orientation.

Numerous other types of structural or surface features may be used toenable the MCD 1520 to be docked in any one of multiple positions. Forexample, the dock 1510 may include cut-outs or recess formations thatform template retention structures to retain the MCD 1520 in a selecteddocked position. As an alternative or variation, surface retentionfeatures may be used to hold (or facilitate retention) of the MCD 1520in position.

In more detail, FIG. 15B and FIG. 15C illustrate another implementationin which surface features may be used to mechanically retain the MCD1520 on the platform 1512 of the dock 1510. In particular, an embodimentsuch as shown may provide that the back face 1562 of the MCD 1520 (oralternatively the platform 1512 of the dock 1510) includes surfaceprotrusions 1532. The platform 1512 (or alternatively the back façade1562) may include aligned retention recessions 1534. Two or more sets ofprotrusions 1532/recessions 1534 may be provided to enable the MCD 1520to be docked in alternative positions (e.g. portrait or landscape). Forexample, the platform 1512 may be configured to include indentationsthat align to receive corresponding protrusions 1532 on the back face1562 of the MCD 1520. The back face 1562 may include alternativeformations to enable the MCD 1520 to be docked in either the landscapeor portrait mode.

FIG. 15C illustrates another variation in which the platform 1512 of thedock 1510 includes a set of insertive clasps 1580 which may secure intocorresponding receiving apertures on the back face 1562 of the MCD 1520.As with previous embodiments, the back face 1562 may include differentsets of apertures to enable the device to have alternative dockingpositions. The clasps may be implemented in any one of many ways. Forexample, each clasp 1580 may be implemented in the form of opposingtongs that bias when pushed towards one another. When biased, the tongsmay be inserted into one of the apertures, where they release andretain. In one implementation, different sets of mechanical clasps mayserve to retain the MCD against the dock in portrait or landscape mode.

While mechanical retention features are described with FIG. 15A throughFIG. 15C, other embodiments described below utilize magnetic clasps ormagnetic retention features. In one embodiment, the dock 1510 includesan arrangement of magnets which retain metal elements in the back face1562 of the MCD 1520. Embodiments described below describe various otherarrangements of magnets which may be combined with one or both devicesto retain the two devices in alternating docked positions.

A method such as described with FIG. 14 may be described in context ofelements described with other figures, and specifically of FIG. 15Athrough FIG. 15C. Accordingly, reference may be made to elements ofthose figures for purpose of illustrating suitable elements forperforming a step or sub-step being described. In step 1410 providesthat a programmatic determination is made to detect an orientation ofthe MCD 1520 when rested or mounted onto the platform 1512 of the dock1510. In one implementation, resources on one or both devices may detectthe orientation of the MCD 1520, and then respond accordingly. Thefollowing illustrate implementations: (i) the MCD 1520 may utilizesensors to detect its own position, then configure its operations (andoptionally communicate with the dock 1510) as to the configuration oroperations performed; (ii) the MCD 1520 may use detectors that detectalignment with corresponding elements on the docking station, and basedon which detectors make contact, determine its own orientation; (iii)the dock 1510 may detect the MCD's position and communicate the positionback to the MCD 1520; and/or (iv) the dock 1510 detects informationusing alignment contacts (see item (ii)) or sensors (e.g. opticalsensors) that is then communicated to the MCD 1520 where it is used todetect orientation on the MCD. Thus, for example, under one embodiment,the MCD 1520 includes a sensor or sensor arrangement (e.g.accelerometer) to detect its own position. As another example, the MCD1520 may include sensors or detectors that detect contact with the dock.Depending on which detectors are active, the orientation may bedetermined. Similar arrangements may be provided as an alternative oraddition on the dock.

Resources for performing orientation detection may vary, depending onimplementation or variation. In an embodiment, metal contacts may beprovided on the platform 1512 of the dock 1510 and on the back face 1562of the MCD 1520. For example, optionally, metal contacts 1555 on theplatform 1512 align with corresponding contacts 1556 on the MCD 1520.The determination of the docked position may be reflected by whichcontacts are energized on one or both devices. In one implementation,the same contacts for establishing the continuously conductive signalpath between the dock and the MCD may be used to identify theorientation of the MCD in the docked position. For example, the positionof the MCD may be reflected by the pattern of metal contacts that areactually in use (or not in use) to pass power or data between thedevices.

As an alternative, the MCD 1520 may utilize an accelerometer todetermine the tilt and thus the position of the device. As anotheralternative, magnetic reed switches or Hall effect switches may beprovided on the dock to sense the presence and/or orientation of theMCD. Such an implementation may be facilitated when magnets are alsoused to retain the two devices in the docked position.

In step 1420, functionality of one or both devices is altered by thedetected orientation of the MCD 1520 placed on the dock 1510. In anembodiment, one or both of the docked devices includes resources toselect, alter or otherwise configure functionality on one or bothdevices based on the detected orientation of the MCD when docked. In oneembodiment, a processor of the MCD selects or otherwise configures oneor more operations that are to be performed based on its determineddocking configuration. On the MCD 1520, the alteration of thefunctionality may correspond to, for example, (i) execution of anapplication or set of instructions, (ii) implementation of a hardwareand/or software-based mode setting. Likewise, on the dock 1510, similaroperations/steps may be performed. When docked, the orientation of theMCD may be serve to configure functionality of the respective dockeddevices to operate independently of the other docked device, or tocombine/share functionality or resources. Numerous examples are recitedbelow.

Optionally, step 1430 provides that the MCD's position on the dock maybe altered after the device is docked. In an implementation when, forexample, retention and/or mechanical features are used to retain the twodevices, the user may move the MCD from, for example, the portraitposition to the landscape position. In another implementation whenmagnetic clasps are used to retain the two devices together, the MCD maybe moved from the portrait position to 45 degrees of vertical, thelandscape position, or one or more positions in between.

In an embodiment, step 1440 provides that functionality of one or bothdevices is re-altered by the detected orientation of the MCD 1520 dockedon the dock 1510, in a manner such as described with step 1420.

As an alternative or variation, the orientation may be altered byremoving the device. But the docking action establishes a pairingbetween the devices that extends to a first instance of the MCD beingdocked in a first position, then removed and re-docked in a secondposition.

The following examples are illustrative of how embodiments may beperformed to implement states, modes or functionality (eitherindependently or cooperatively) on one or both devices in the dockedposition. Different states for the device and dock (depending on thedevice position/orientation). As the orientation or manner in which thedevice is controlled is user-controlled, the state/mode or functionalityof the device(s) may be controlled by the user through manualpositioning or orientation of the MCD on the dock.

In one implementation, two orientations may be possible (e.g. landscapeversus portrait), and the user's selection of, for example, one state oranother is communicated through the selected orientation. For example,the device state for either of the docked devices may be selected by theuser simply setting the back face of the MCD on the receiving surface ineither landscape or portrait mode. As another example, the user can setthe MCD 1520 down in a portrait position to implement a firstfunctionality, such as the display of a large clock, information from apre-selected or designated internet site (e.g. weather), or images froma photo-album. The user may alternatively place the MCD 1520 down in thelandscape position, to implement another one of the functionalities ormodes/states. For example, when the MCD is placed in the landscape modeon the dock, the MCD may display a calendar or so-called ‘Today’ screen.

In one embodiment, the user can switch the position of the MCD 1520while it is in the docked position. Still further, the changing of thedevice while being in the docked position may in and of itself be aspecial type of input. For example, the user altering the orientation ofthe MCD while docked may signify a state change that is different thanhad the user originally placed the device in the dock 1510 in the newposition.

According to one or more embodiments, the MCD 1520 is a telephony devicein that it is capable of receiving incoming calls (e.g. over cellularconnection) or placing outgoing calls. In such embodiments, the selectedorientation of the device on the dock may affect call handling routinesand functionality. In one implementation, the call handling of thedevice can change when docked—for example if the MCD 1520 receives anincoming call while docked, the device may configure itself to (i)enable the call to be answered or handled easily without de-docking thedevice, and (ii) enable the user to leverage resources or capabilitiesof the dock for use in connection with the incoming call or relatedtasks. For example, the user may be enabled to lightly tap a display ofthe MCD in order to direct the MCD to enter speaker-phone mode (withoutdislodging the device from the dock 1510), and optionally use thespeakers of (or attached to) the dock.

As another illustration, the device may be configured to enable mediaplayback through the dock 1510. But in call handling mode, the speakerphone mode may automatically suspend any music which is playing on thedevice, to permit the user to place or answer a call.

As another alternative or additional feature, when the MCD 1520 isdocked in a particular orientation, the MCD 1520 may be triggered toperform or display information such as: (i) Internet or network content,such as stock, weather or news; (ii) provide a clock; (iii) displayslide show of pictures or images; (iv) display calendar or task lists orevent list; or (v) provide generic personalized displays by them, suchas for ‘work’, ‘personal’ or ‘finance’. Still further, state informationmay be implemented, such as by way of reducing the power consumptionand/or switching select components of the device off. For example, whenthe device is docked, one or more components (display, cellular radio,GPS radio) may be switched on (or alternatively off). As mentioned, theposition of the MCD 1520 on the dock may determine the function, stateor mode of operation that the device has.

Still further, as another alternative or addition, an orientation of theMCD may be used to indicate a presence or status of the user to receiveonline or other forms of communications. For example, the user maycorrelate the orientation of the MCD with an online status for receivingInstant Messages or text messages (e.g. landscape mode means the personis away, while portrait means the person is available to respond oronline). Likewise, orientation may be used to determine whether the useris willing to accept incoming phone calls, or whether incoming phonecalls should be transferred to voicemail or elsewhere. Still further, amessage reply functionality, such as enabling text-message reply to anincoming call, may be switched on, off or configured based on theorientation of the MCD on the dock.

In an embodiment, the position of the MCD 1520 on the dock may alsoaffect the state or functions performed by the dock 1510. As examples,the orientation of the MCD 1520 in the dock may signal the dock toconnect to a particular computer via a wireline (e.g. Universal SerialBus) or wireless connection. As an alternative or addition, the dock1510 may wirelessly and/or through wireline connect to more than onecomputer or device. The orientation of the MCD 1520 when docked may actas a form of selection input to enable the user to select one computerover another to communicate with or access, via the dock or throughcredential information received from the dock.

Other examples of functions or mode-settings that may be triggered orotherwise selected from the position of the MCD on the dock include: (i)media playback (audio or video) via a particular input source (e.g.analog input, streaming, wireless communications, via USB or FIREWIREconnector); (ii) media output through dock connections (e.g. dock may beconnected to speakers or to large display device); (iii) music streamedfrom device; (iv) wired keyboard/mouse could be connected to the dockand enabled for use with the MCD when selected.

As mentioned, the user's action corresponding to altering theorientation of the MCD 1520 when docked may in and of itself serve as aform of input. For example, when the device has one orientation, onefunctionality is enabled or selected for one or both devices, then whenthe user rotates the device on the dock to a new position, the userinterface can switch to a default setting. The user can then change theorientation of the MCD 1520 back to an original position (or to a thirdposition) in order to (i) resume, for example, a previous functionalityor mode setting, (ii) perform a new function or achieve a new modesetting.

Device Block Diagrams

FIG. 16 is a simplified block diagram of a MCD, according to anembodiment. A MCD 1600 may be configured to include any of thefunctionalities or capabilities described with other embodiments,including the ability to receive electrical signals (power and/or data)using conductive or inductive signal paths. Thus, as mentioned withother embodiments, the MCD 1600 may correspond to, for example, a ‘smartphone’, a mobile companion, a media player, a digital camera, or a GPSunit (or to a multi-function device that can perform as many of thedevices described).

More specifically, one or more embodiments provide that the MCD 1600 maycorrespond to a mobile telephony/data messaging computing device, suchas a cellular phone or mobile device with voice-telephony capabilities(sometimes called “smart phone”). A computing device such as describedmay be small enough to fit in one hand, while providing cellulartelephony features in combination with other applications, such asmessaging, web browsing, media playback, personal information management(e.g. such as contact records management, calendar applications, taskslists), image or video/media capture and other functionality. Otherexamples of functionality that may be provided from the MCD 1600 includeaudio and/or video playback or Global Positioning Services (GPS) asprimary or enabled functions. The MCD 1600 may have numerous types ofinput mechanisms and user-interface features, such as keyboards orkeypads, multi-directional or navigation buttons, application or actionbuttons, and contact or touch-sensitive display screens or buttons. Inthe case of data messaging/communication devices, specific types ofmessaging or communications that may be performed includes messaging foremail applications, Short Message Service (SMS), Multimedia MessageService (MMS), and proprietary voice exchange applications (such asSKYPE). Still further, the MCD 1600 may correspond to numerous othertypes of computing devices, such as to a notebook computers, anultra-mobile computer, or a personal digital assistant.

According to an embodiment, the MCD 1600 includes one or more processors1610, memory resources 1620, a display assembly 1628, one or morecommunication ports 1630, and a power module 1640. In an embodiment, theMCD 1600 includes a signal handler resource 1650, which includeshardware and logic for accepting and/or transmitting power or datasignals using any of the signal paths described with previousembodiments. As another option, the MCD 1600 includes one or moredetectors 1660 (or sensors) for detecting orientation or position of theMCD 1600 when the device is docked to the accessory device.

The processor 1610 may include or communicate with the signal handlingresource 1650 to enable some or all of the signal handling capabilitiesfor enabling receipt or transmission of signals using signal paths suchas described with embodiments described above and elsewhere. Thecommunication ports 1630 may include wireless or wireline ports.Wireless communication ports may be implemented through, for example,local wireless communication protocols such as provided by BLUETOOTHstandards, Wireless Fidelity (802.11(b) or (g)). The wirelesscommunication ports may also communicate over a cellular network. Morespecifically, the MCD 1600 may include one or more wirelesscommunication ports to provide wireless connectivity of a particulartype (or types) for purpose of carrying out any one or more types ofwireless operations. For example, the communication port 1630 mayinclude or correspond to (i) a Wide Area Network (WAN) radio module forsending and receiving cellular voice/data, (ii) a local wirelesscommunication port such as Bluetooth or wireless USB, (iii) an infraredport, (iv) a Global Positioning System radio, and/or (v) a WiMAX radio.

The memory resources 1620 may, for example, include Flash memory, RandomAccess Memory, and/or persistent memory (i.e. ROM). The memory resources1620 include instructions and data for implementing functionality andprogrammatic actions such as provided with any of the embodimentsdescribed. Optionally, the memory resources 1620 may carry databases ordata stores of records that contain active data items (such as describedabove) for synchronization or communication with a primary computer,and/or enable actions on such data items of saving the data items.

According to an embodiment, the signal handler resource 1650 includeshardware for receiving or transmitting a power signal and/or a datasignal (either modulated or combined as one signal) to and/or from thedock. In an embodiment in which the power or data signal is conveyedthrough a continuously conductive signal path, the signal handlerresource 1650 includes circuitry, such as a recharging circuit and/orelements to treat incoming signal. In an embodiment in which the poweror data signal is conveyed through an inductive signal path, the signalhandler resource 1650 includes one or more coils and various hardwareelements/logic for converting inductive modulations into current.Additional details of components and elements for signal handlerresource 1650 to enable an inductive signal path is detailed withvarious embodiments described above. In one embodiment, the signalhandler resource 1650 is configured to receive a power signal forpurpose of either powering other components (e.g. display assembly 1628)of the MCD 1600, or to recharge the battery of the power module 1630. Inone implementation, the incoming power signal may be treated usingcircuits and components that are separate from a central processor ofthe MCD 1600. Thus, processor 1610 may include more than one unit orresource. In one implementation, for example, the MCD 1600 includes botha signal processor (which may be incorporated with the signal handler1650) and a central processing unit (CPU).

As an addition or alternative, the signal handler resource 1650 mayextend or transmit a power signal to the attached accessory device (e.g.to the sticky device shown with FIG. 34) using charge stored in thebattery module 1630.

As described elsewhere, an embodiment provides that the MCD isconfigured to use the signal handler resource 1650 to convey and/orreceive some data that enables subsequent communications between thedevices. This data may include credential data 1652, which enablesubsequent wireless communications using, for example, a local wirelesscommunication link via one of the local wireless communication ports1630. The credential data 1652 may be stored within a portion of thememory resources and made available to the processing resources forinclusion or use with functions performed by the signal handlingresource 1650. In one embodiment, the signal handling resource 1650 iscapable of communicating at least some of the credential data through amodulated power signal. As an addition or variation, the signal handlingresource is capable of recognizing or using the credential data 1652 toidentify and pair with the dock.

As described with embodiments of FIG. 14 and FIG. 15A through FIG. 15C,the MCD 1600 may be configured to detect information about itsorientation when it is placed on the dock 1510 (see FIG. 15). In oneembodiment, the detectors 1660 are provided in the form of sensors thatindependently detect the orientation of the MCD 1600. For example, thedetectors 1660 may correspond to accelerometers or vertical positionsensors that detect the orientation of the MCD 1600 at any giveninstance. In another embodiment, the detectors 1660 sense or communicatedata or signals to electrical or conductive pads that are positioned onan exposed surface of the dock. Thus, the position of the MCD may bedetected by determining which detectors 1660 and/or sensors orconductive pads are in contact when the two devices are docked.

Information identifying the orientation of the MCD 1600 when docked mayaffect various operations or modes/states of the MCD and/or itscomponents. The detectors 1660 may signal or communicate the orientationinformation 1662 to the processor 1610 of the MCD. In oneimplementation, for example, the processor 1610 is configured to use theorientation information 1662 to signal a display state 1629 to thedisplay assembly 1628. The display assembly 1628 may, for example, beswitched between portrait and landscape mode in response to the signal.

FIG. 17 is a simplified block diagram of an MCD configured to include asignal handing resource that is capable of receiving and/orcommunicating signals through an inductive signal path, under anembodiment. The MCD 1700 may include a signal handling resource 1750 forreceiving or communicating power and data through induction. The signalhandling resource 1750 may correspond to the corresponding elementdescribed with an embodiment of FIG. 16.

In an embodiment, the signal handling resource 1750 includes one or morecoils 1752 that form a terminal of a corresponding inductive signalpath. Additionally, the signal handling resource 1750 includes detectand conditioning circuits 1754, power circuits 1756 and a signalprocessor 1760 (or processing resources) for handling incoming andoutgoing signals using the inductive signal path.

Among other functions, an embodiment provides that the signal processor1760 implements a data protocol by which data may be communicated and/orinterpreted through the inductive signal path, enabled in part throughthe coil 1752. The signal processor 1760 may also act as a control forreceiving/communicating power. To this end, it may enable power circuits1756 which treat the incoming signal path. The signal processor 1760 maymonitor voltage and current at various points of the power circuit andcontrol adjustments as necessary. The power circuits 1756 may supplypower across a power bus 1757 to device electronics 1770, to power thecomponents independently and/or to recharge the battery of the device.The signal processor 1760 may use data bus 1762 to exchange data withanother processing resource (e.g. CPU) of the device. This data maycorrespond to, for example, credential information, or the informationregarding data received from the dock (e.g. confirmation of credentialinformation exchange).

Additionally, the MCD 1700 may be configured to combine detectors 1754to detect and signal information from corresponding pads or contactspositioned on the dock. The signal processor 1760 may detect whichdetectors 1754 change states as a result of contact with correspondingelements on the dock. This information may be signaled across the databus 1762 as orientation information. As described with an embodiment ofFIG. 14, the orientation information may affect states, modes oroperations of one or more components of the device electronics.

The signal processor 1760 may perform various other functions. In oneimplementation, the signal processor 1760 monitors voltage and currentlevels of the power circuits. The signal processor may also receivepower voltage via an intermediate regulator form the power circuits1756.

FIG. 18 is a simplified block diagram of a dock, under an embodiment.The dock 1800 may correspond to any of the docks described with otherembodiments herein. In particular, a dock as described may be used toimplement (depending on the embodiment) a conductive or inductive signalpath for communicating power and data with a MCD such as described withFIG. 17. In an embodiment, the dock 1800 includes processing resources1810, a signal handler 1820, memory resources 1830, and a power resource1840. The dock 1800 may also include one or more communication ports,including a wireless communication port 1842 and/or one or more wirelinecommunication ports 1844.

The processing resources 1810 may enable intelligent operations, such asauthenticating or pairing with the MCD 1700 (see FIG. 17) (e.g. over awireless link) and/or data sharing/synchronization operations (with MCD1700). In one variation, the dock 1800 is also capable of interfacingwith a computing resource (e.g. other device or computer) to enablesynchronization or data sharing operations between the MCD 1700 andthird device, or between the dock and the third device. In anembodiment, the processing resources 1810 may correspond or include asignal processor which is able to receive or transmit data throughmodulations in the power signal.

In an embodiment in which a continuously conductive signal path is used,the signal handler 1820 includes circuits and elements for enabling aconductive contact with corresponding elements on the façade of the MCD.Additionally, one embodiment provides that the signal handler 1820 maysignal data with power by modulating the power signal that isconductively transmitted. In an embodiment, the data signal may also becommunicated through the signal handler 1820 using an independent andcontinuously conductive signal path.

In an embodiment in which an inductive signal path is used, the signalhandler 1820 includes circuits and elements for enabling an inductivecoupling with corresponding elements residing within a panel or housingof the MCD. The signal handler 1820 may include one or more coils fortransmitting and/or receiving power or data. As described, the powersignal communicated through the magnetic coil may optionally bemodulated in a manner that carries or communicates data. Thus, thesignal handler 1820 may communicate or receive data using a power signalcarried over an inductive signal path.

The power resource 1840 may handle power received through a standardoutlet. As an alternative or addition, the power resource 1840 may drawpower from another computing device. Still further, the power resource1840 may include batteries that provide power for the dock and otherdevices.

The wireless communication ports 1842 may be provided in the form of astandardized port, such as defined by the BLUETOOTH 2.0 or WIRELESS USBstandards. The physical ports may also be standardized, such as providedby USB or FIREWIRE standards.

Optionally, the dock 1800 includes an orientation detection mechanism1812 that may detect the orientation of the MCD in the docked position.As an addition or alternative, the orientation detection mechanism 1812detects whether the MCD is present (i.e. docked). As described withother embodiments, the orientation detection mechanism 1812 may useinformation that is indicative of the orientation of the MCD in thedocked position to perform or configure a state or mode or operation.Alternatively, the dock 1800 may communicate the orientation informationto the MCD.

Among possible functions that the dock may perform, the dock may send orreceive wireless communications 1811 with the MCD. Such communicationsmay accomplish various tasks or operations, including (i)synchronization or communication of data files or records 1861 (e.g.synchronize contacts and emails), (ii) establish a paired relationshipwith the MCD for subsequent operations using credential information 1863and device communications 1864, (iii) establish a paired relationshipbetween the MCD and a third computing device connected to the dock (e.g.enable BLUETOOTH or wireline communication with attached personalcomputer), (iv) serve as a pass-through or data interface with anotherdevice (e.g. television of display screen) by forwarding communications1862 to a third computer (e.g. personal computer or laptop), and/or (iv)exchange of data to share or provide resources or extend functionalityof the MCD (e.g. enable playback of media data 1865 residing on thedevice by routing audio to speakers connected to dock).

One primary purpose that the dock 1800 may serve is to recharge or powerthe MCD using power communicated through the signal handler 1820. Stillfurther, an embodiment provides that the dock 1800 detects anorientation of the MCD and then communicates the orientation informationto the MCD.

While an embodiment of FIG. 18 is descriptive of an accessory devicethat corresponds to a dock, it should be apparent that other forms ofaccessory devices may include similar components or functions. Forexample, as described with an embodiment of FIG. 34, an accessory devicemay be provided in the form of a “sticky-back” device. Such a device mayuse, for example, the signal handler 1820 to conductively or inductivelyreceive power or data. Such a device may also perform wirelesscommunications with the MCD to synchronize records, perform mediaplayback and/or otherwise share other forms of data (e.g. provide GPSdata, receive images etc.)

Thus, with the examples recited, an embodiment provide that the MCD 1700(see FIG. 17) may be configured to (i) receive power from an accessorydevice, such as a dock 1800, and/or (ii) perform wireless communicationswith the accessory device (i.e. dock 1800 or other device) using a localwireless communication port. As an addition, the MCD may use the powersignal or the connector-less medium (as described with continuouslyconductive or inductive signal path) to exchange and performprogrammatically at least some of the steps to authenticate or authorizethe wireless pairing and communication. In some cases when, for example,the accessory device requires power, the MCD may supply the power,using, for example, the inductive signal path such as described withother embodiments.

Magnetic Clasping

Numerous embodiments described herein provide for a MCD thatelectrically couples to a dock through surface contact. In suchembodiments, there is an absence of connector forces or mechanisms thatare traditionally used to retain a device against a dock. For example,one conventional design provides for portable computing devices tointegrate connectors into surface edges of the device. The devices maythen be placed onto a receiving surface of a docking station so that thedevice's connector (usually female) receives the extended connector fromthe dock. These conventional device-to-docking designs require users toalign the devices so that the connector ports of the computing deviceand dock are in alignment. In addition to requiring efforts from a userto align and then insert the device onto the appropriate region of thedock, the manner in which the connectors of the device and dock matemust consider forces that fatigue or break connectors as a result ofweight or withdrawal of the computing device from the dock.Additionally, such connectors can occupy significant thickness anddimension in the housing of the MCD.

It should be noted that on a most simple level, magnetic claspingbetween an MCD and any of the dock or any other device, may be performedto simply retain the MCD against the dock (e.g. cradle) or otheraccessory device (e.g. modem). Thus, some embodiments provide thatmagnetic clasping, as described with any of the embodiments herein maybe used to simply retain one device against the other. Morespecifically, some embodiments include distributing magnets and ferrousmaterials between MCD and dock (or other coupled devices) in order toenable retention of the two devices together. Various configurations forimplementing magnets and ferrous material on the MCD and/or dock may beutilized in accordance with embodiments described with, for example,FIG. 19-34. Features such as orientation manipulation, optionallycombined with orientation detection may also be included in connectionwith magnetic clasping. In some embodiments, these and other featuresmay provide for incorporation of magnetic clasping and/or orientationplacement and/or detection without signal communication (inductive orotherwise). Other embodiments may provide for the inclusion of inductiveor conductive signal transfer with magnetically coupled devices.Numerous other variations and combinations described elsewhere in thisapplication may also be implemented.

In contrast to these and other conventional approaches, embodimentsdescribed herein enable a connector-less coupling that physicallyrestrains the MCD against the dock, while enabling transmission of powerand/or data between the devices. In particular, embodiments describedherein facilitate the user's involvement in docking the MCD with thedock, by enabling the user to perform a simple action of placing the MCDon a receiving surface of the dock. The user is not required to makeeffective a mating of connectors between the MCD and the dock. Thus,requirements of the user to align contact elements or slots is reducedor eliminated. The user does not have to align connectors or forcemechanical connections between connectors of the dock and MCD. Moreover,mechanical issues relating to fatigue or breakage of the connectors iseliminated.

The placement of a portable or MCD onto a dock may be passive or active,depending on design and implementation. In a passive surface matingscenario, gravity is the primary force that holds the device inposition, so that appropriate surfaces on the MCD are in contact withcorresponding points of the dock. In particular, embodiments provide forthe retention of the MCD and the dock to be effective using any one ormore of (i) mechanical retention using support structures and/frictionalpressures (with gravity or other forces), (ii) mechanical clasping,and/or (iii) magnetic fields or clamping.

As described previously, mechanical retention may be provided by ledges,platforms, shelves or other surface features. The mechanical retentionmay be aided or enabled with features for creating frictional pressure.Specifically, frictional pressure may be facilitated by surface featuresprovided on the MCD or dock (e.g. see FIG. 15B). Surface features, suchas indents, bumps, and/or ledges may be used to align and hold the MCDin position on the receiving surface of the dock. Surface features mayalso be used to enhance electrical contact between the MCD against thedocking.

As an alternative to mechanical retention features, magnetic claspingmay be used to firmly grip two devices together in anyone of multiplepossible or desired positions. Moreover, magnetic clasping enables theuser to simply place the MCD onto the receiving surface of the dock.

According to an embodiment, magnets may be combined with the dock (oroptionally with the MCD) in order to clasp the two devices together whendocked. Such magnetic clasping may offer several benefits, including theability to enable the orientation by which the MCD is docked to bealtered. As described elsewhere, some embodiments provide that theorientation of the MCD on the dock may be used to affect the state, modeor functionality of the MCD and/or dock. Additionally, magnetic claspingamongst the devices may enhance the ability to enable connector-lesssignal exchange between the MCD and the dock, as the MCD may simply beplaced on the dock for retention. Thus, under one implementation, whenplace within a certain allowable area, the magnets will pull the deviceinto the proper position for the connector-less signal exchange andcharging.

FIG. 19 depicts a configuration for a back face of a MCD, under anembodiment. In one embodiment, a housing surface (i.e. back façade 1915)of the MCD is provided with material that is attracted to magneticmaterials. However, to enable the device to be portable and unaffected,an embodiment provides that no magnetic material is provided on the MCD(so as to avoid, for example, collection of debris). Rather, anembodiment provides that the back façade 1915 of the MCD includesferrous tabs 1912. The ferrous tabs 1912 may be provided on or near anexterior of the rear façade 1915. For example, some ferrous material maybe combined with a thickness of the housing shell, or glued to anexterior of the housing shell. Various spatial arrangements may beprovided for the ferrous tabs 1912. For example, the distribution of theferrous tabs 1912 may correspond to various geometric shapes.Alternatively, a portion of the back face 1915 may include a ferrouslayer or thickness.

FIG. 20 depicts a top view of a receiving surface for a dock thatincludes an arrangement of magnets. In an embodiment, a receivingsurface 2010 of the dock includes an arrangement of magnets 2012. Inthis way, the receiving surface is able to provide a magnetized landingspace for receiving and docking with the back face 1915 (FIG. 19) of theMCD. The receiving surface 2010 may use magnets and/or surface ormechanical features in order align and hold the back façade 1915 of theMCD. In particular, the alignment may make effective the magneticclasping between magnets 2012 and the ferrous tabs 1912. Among otherobjectives, an embodiment enables a user to simply place the back face1915 on the retention surface 2012 in order to make effective themagnetic coupling.

With reference to FIG. 19 and FIG. 20, one or more embodiments providefor the use of an inductive signal path to transfer power and/or databetween the two devices. The inductive signal path may be enabled byembedding coils and related components within the back façade 1915 ofthe MCD and the receiving surface 2010 of the dock. Thus, inductivesignal transmission may be enabled through use of magnetic mechanicalcoupling, as shown and described.

As an alternative or addition, conductive signal transmission may beenabled between the MCD and the dock. In such an embodiment, the use ofthe conductive signal path is enhanced because the magnet couplingprovides an active physical retention force between the surfaces of thetwo devices.

FIG. 21 is a side cross-sectional view of a dock 2000 with magnets 2012for providing the receiving surface 2010, under an embodiment. Themagnets 2012 may be provided in apertures or openings 2022 just underthe receiving surface 2010. This enables the receiving surface 2010 tobe smooth, while at the same time being able to receive and magneticallyretain the MCD when it is dropped on the receiving surface. A body 2015of the dock 2000 may align the receiving surface 2010 to receive theback face 1915 of the MCD. In one implementation, the receiving surface2010 may be slanted at least partially in a vertical direction, althoughalternative variations may provide for the receiving surface to behorizontal.

One benefit of using magnetic coupling is that magnets can bedistributed to retain the MCD in a manner that enables both (i) multiplecoupled orientations (e.g. four positions, eight positions), and (ii)self-alignment of the MCD in one of the multiple possible orientations.In particular, the magnet or ferrous material arrangements may beconfigured in order to attract the MCD to a particular orientation, andrepel it from orientations that are in between attracted positions.Thus, discrete orientations are enabled, and the devices may usemagnetic forces to ‘self-align’. By enabling the MCD to occupy differentorientations when docked, orientation-dependent functionality such asdescribed with embodiments of FIG. 14 and FIG. 15A through FIG. 15D, maybe enabled.

With magnetic coupling, alignment of the desired regions on the backface 1915 of the mobile computer and the receiving surface 2010 of thedock 2000 are desirable, because the alignment betters or makeseffective the magnetic forces to achieve the coupling. Mechanicalgeometry may be used to achieve desired prevision in alignment when twodevices are mated, so that the two mated surfaces are aligned for themagnetic coupling to be effective. While embodiments contemplatenon-magnetic, mechanical features for use in aligning and/or supportingthe MCD in a docked position with use of magnets, the use ofnon-magnetic features to facilitate magnetic coupling may have someundesirable results. Specifically, surface features and mechanicalretention features to facilitate magnetic alignment may preclude orinhibit the ability of the user to alter the position of the MCD whendocked (as desired with, for example, embodiments of FIG. 14).Additionally, surface features and mechanical retention features preventthe receiving surface of the dock from having a smooth and aestheticallyappealing surface.

In order to facilitate alignment, it is also possible to use strongmagnets on both the receiving surface 2010 and the back face 1915 of theMCD. However, for many applications, the containment of magnets in theMCD is undesirable (e.g. for devices that are carried in pockets ofpersons). Using magnets on both sides allows magnetic polarity tofurther restrict the allowable orientations for the placement of the MCDon the dock.

As an alternative to surface or mechanical features, or magnets on bothmated devices, some embodiments provide for an alternative configurationof magnets and ferrous materials in order to achieve focused and alignedmagnetic coupling between the two docked devices. FIG. 22 illustratesone embodiment in which ferrous cups 2050 are provided in connectionwith the magnets 2012 of the dock, under an embodiment. The ferrous cups2050 serve to focus the magnetic fields of the magnets 2012. The focusedmagnetic fields better enable the receiving surface 2010 to align withthe back face 1915 of the MCD.

FIG. 23 illustrates an embodiment in which a relative geometry ofmagnets and tabs may be offset to create a magnetic locking effectbetween docked devices, according to an embodiment. In particular, oneor more embodiments recognize that the magnetic fields 2102 where thetabs are attracted to are relatively wide, allowing the tabs 1912 tomove in a large area. An embodiment of FIG. 23 illustrates placement ofan arrangement of tabs 1912 to have a larger diameter than the fourmagnets. Such a geometry forces each tab 1912 to only align to the outerportion of the corresponding magnetic field. The result is that thearrangement tightens the alignment and coupling considerably.

FIG. 24 shows another orientation where a square magnet 2205 is providedon the receiving surface 2010 in order to constrain a slightly smallerround tab 2203 (provided on the back façade 1915). A square magnet mayretain a circular tab 2203 more tightly with less permissible movement,as compared to circular magnets and tab configurations.

FIG. 25 depicts the façade 1915 of the MCD with representativeelectronic components 2310 and 2312, according to an embodiment. Therepresentative electronic components 2310 and 2312 may be embedded atdifferent layers within a housing of the device (underneath the exposedback façade 1915). The ferrous tabs 1912 may be positioned to circumventthe electronic components 2310, 2312.

FIG. 26 depicts the back façade 1915 of the MCD with an enhancement fordevice orientation detection. The enhancements may be in the form ofsensors 2315, which align with slugs 2710 shown in FIG. 27. Contact orproximity between sensors 2315 and slugs 2710 may be detectable on thesensor or slug, and then used to trigger or signal information thatcorrelates the particular slug 2710 or sensor 2315 that is affected withan orientation. In one embodiment, the alignment of sensors 2315 maycorrespond to positioning of different sets of slugs 2710. Thus,orientation detection may be provided by detecting which slugs 2710 arealigned with sensors 2315 when the MCD is docked with the dock.

FIG. 28 and FIG. 29 illustrate side views of how the dock 2000 can beconfigured in positioning the slugs 2710 with respect to the receivingsurface 2010. In FIG. 28, a set of slugs 2710 are positioned betweenmagnets 2012. In FIG. 29, the set of slugs 2710 are shown disposedbetween cups 2050. As explained with an embodiment of FIG. 14, theorientation of the MCD on the dock may be used to implement or selectfunctionality or mode or state of one or both devices.

Magnetic Ring

One or more embodiments also provide for use of a ring (e.g. ferrousring) in order to enable free rotation (not limited to 90 degree) of theMCD to anyone of many possible orientations when the device is docked tothe dock. FIG. 30 illustrates a ferrous ring 2810 formed into a regionof the back façade 1915 of the MCD. The ferrous ring 2810 may circumventa substantial region or area on the back façade 1915. Any one of themagnet configurations shown for the dock may be used to enable the MCDto have ‘free rotation’ when docked onto the receiving surface of thedock. Thus, while some embodiments that utilize magnetic coupling mayprovide for 2 or 4 positions, an embodiment such as shown with FIG. 28may enable the MCD to have almost any position defined by the placementof the ring 2810 on the receiving surface of the dock. Moreover, asdescribed with an embodiment of FIG. 14, certain positions of the MCDmay have associated therewith a functionality or mode setting. Suchfunctionality or mode setting may be implemented automatically when thedevice is rotated or placed in the assigned position on the dock 2000.Still further, the ring 2810 enables the user to move the MCD whiledocked like a dial, without breaking contact with the receiving surfaceof the dock.

In FIG. 31, components 2812, 2814 for enabling signal path transmissions(e.g. inductive) for communicating power or data is shown about theferrous ring 2810 on the back face. The components may be embeddedwithin the housing, so as to be provided beneath the back façade 1915.

In FIG. 32, orientation or position detection sensors 2830 are shown tobe contained in the housing of the MCD. In one embodiment, the sensorsshown detect a position of the slugs 2710 on the receiving surface 2010of the dock.

FIG. 33 illustrates a MCD 1900 docked onto the dock 2000 using magneticclasping, according to one or more embodiments described. In the exampleprovided, the MCD 1900 is assumed to have a portrait orientation,although alternative orientations are possible (e.g. landscape, 45degrees from vertical, 30 or 60 degrees from vertical), particularlywhen magnetic clasping is used. In an embodiment shown, the dock 2000includes using magnets 2012 in anyone of the configurations described toretain the MCD 1900.

Because the housing 1920, of the MCD 1900, attaches to the dock 2000 viamagnetic clasping, rather than mechanical latching, the receivingsurface 2010 of the housing 1920 may be made relatively smooth. Forexample, the housing 1920 (and/or the surface of the dock 2000) may bemade of a slippery material such as Teflon, PFA, FEP, Acrylic, Dacron,Nylon, PVC, flouropolymers, and/or Rulon. Thus, the user may dock theMCD 1900 by simply dropping the device onto the dock 2000, such that thehousing 1920 makes contact with the receiving surface 2010.

FIG. 34A illustrates a perspective view of a ring interface for amagnetic clasp, according to an embodiment. The magnetic clasp 2100includes four magnets that 2012 are positioned in a circularconfiguration around a ring 2030. The magnetic clasp 2100 may beimplemented on a corresponding dock 2000, such that when the housing1920 of a MCD 1900 makes contact with the dock 2000, the magnets 2012“lock on” (i.e., are attracted to) a ferrous ring 2810 (and/or plates)on a housing 1920 of the MCD 1900 to hold the device in place.

While in contact with the dock 2000, the MCD 1900 may be re-oriented toa desired presentation (e.g., either portrait or landscape). Forexample, the ferrous ring 2810 on the housing 1920 may be rotated in acircular manner, over the magnetic clasp 2100, while in constant overlapwith the ring 2030 (i.e., while maintaining contact with each of thefour magnets 2010). According to an embodiment, the magnetic clasp 2100may be flush with the receiving surface 2010 of the dock 2000.Alternatively, the magnetic clasp 2100 may protrude from the receivingsurface 2010 to allow for easier alignment and/or contact with theferrous ring 2810 of the housing 1920.

FIG. 34B illustrates a perspective view of a ring interface withmechanically proud areas, according to an embodiment. The magnetic clasp2200 is similar to the magnetic clasp 2100, with the exception that thering 2030 includes four mechanically “proud” regions 2032, surroundingeach of the four magnets 2012. These proud regions 2032 provide a largersurface area for which the housing 1920 of the MCD 1900 may make contactwith the magnets 2012. In addition, the ratchet-like design of themagnetic clasp 2200 may be useful in orienting or positioning the MCD1900 relative to the dock 2000.

In the embodiments shown in FIGS. 34A and 34B, the four magnets 2012 arepositioned equidistant to one another, in a “diamond” (or “square”)formation. However, the spacing and/or positioning of the magnets 2012may vary depending on device configuration. For example, in alternativeembodiments, any of the following geometric configurations may be used:(i) with one magnet in each of the upper left, upper right, lower left,and lower right orientations; (ii) in a trapezoidal formation; and (iii)with a combination of two magnets (positioned 180 degrees apart) andfour magnetic tabs spaced evenly around the ring 2030.

When docked, one or more embodiments provide for conveyance of powersignals from the dock to the MCD 1900 through use of conductive orinductive signal paths, such as described with other embodiments. Inaddition to the power signals, one or more embodiments provide forconveyance of data concurrently with or through use of the power signal.Still further, in the docked position (and shortly thereafter), the MCD1900 and the dock 2000 may communicate data using a local wirelesscommunication link.

FIG. 35 illustrates an embodiment of a magnetic element which may beused for the magnetic clasping as described in any of the aboveembodiments. The magnetic element 2020 is made up of two bar magnets,2021 and 2023, provided on top of a base layer 2025. The base layer maybe constructed of a low reluctance material, to allow high magneticpermeability. The bar magnets 2021 and 2023 are separated by anon-magnetic spacer 2027, and are arranged in parallel with oppositepolarities facing up. For example, the magnet 2021 is oriented with its“north” pole facing the base layer 2025, and its “south” pole facingupward. In contrast, the magnet 2023 is oriented with its “south” polefacing the base layer 2025, and its “north” pole facing upward. Thus,the magnetic element 2020 effectively functions as a “horseshoe” (orU-shaped) magnet. In certain embodiments, one of the bar magnets 2021 or2023 may be longer (or shorter) than the other.

The magnetic element 2020 may correspond to, and therefore perform thefunctions of, any of the magnets 2012 in the embodiments describedabove. As described in greater detail below, the magnetic properties ofthe magnetic element 2020 provide several advantages when magneticallyclasping a MCD 1900 to a dock 2000. For example, the pairing of two barmagnets in parallel yields a much stronger magnetic attraction (e.g.,double the magnetic force of a single bar magnet).

The horseshoe configuration further allows for the magnetic field 2028,emanating from the magnetic element 2020, to be more locallyconcentrated (i.e., towards the top of the magnetic element 2020).Reducing the overall spread of the magnetic field 2028 may, in turn,mitigate the occurrence and/or effects of magnetic interference in thedock 2000 and the MCD 1900.

For example, magnetic fields produced by the magnets 2012 may induceundesired currents in the electrical components of the MCD 1900 and/orthe dock 2000. This issue may be further complicated duringcommunications between the MCD 1900 and the dock 2000, especially whenthe dock 2000 inductively communicates with the MCD 1900. Because suchcommunications depend on inducing an electromotive force (EMF), changesin the induced EMF (e.g., caused by magnetic fields from the magnets2012) may alter or adversely affect the data being communicated.Localizing the magnetic field 2028 produced by the magnets 2012 may thusallow for more robust communications between the MCD 1900 and the dock2000.

It should be noted that, in certain embodiments described herein, thehorseshoe magnet assembly 2020 may be substituted for an “actual”horseshoe magnet. The actual horseshoe magnet may be unitarilyconstructed from a single piece of magnetized material. For example, theactual horseshoe magnet may correspond to a single bar magnet that isbent or formed into the U-shape configuration.

FIG. 36 illustrates a cross-sectional view of the dock 2000 and MCD 1900along lines A-A, according to one or more embodiments. The dock 2000 mayinclude magnets 2012 that have a horseshoe or U-shape configuration, forexample, as described above in reference to FIG. 35. In alternativeembodiments, the horseshoe magnet assemblies 2012 may be substituted foractual horseshoe magnets.

In the particular arrangement shown, the inner magnetic poles of themagnets 2012 have the same polarity, and the outer magnetic poles of themagnets 2012 have the same polarity. For example, the magnets 2012 areconfigured such that each of the inner bar magnets are oriented withtheir north poles facing upward, and each of the outer bar magnets areoriented with their south poles facing upward. Alternatively, the innerbar magnets may be oriented such that their south poles face upward, andthe outer bar magnets may be oriented such that their north poles faceupward.

The configurations for the embodiments described, with respect to FIG.36, have several advantages. For example, the horseshoe configurationsof the magnets 2012 provide a very strong attractive force (e.g., doublethe magnetic force of a single bar magnet). Thus, the ferrous tabs 1912may be set further from a surface of the housing 1920, to allow asubstantial gap 1950 between the ferrous tabs 1912 and the receivingsurface 2010 of the dock 2000 when a surface of the housing 1920 isbrought into contact with the receiving surface 2010 of the dock 2000.

The deeper placement of the ferrous tabs 1912 may allow for moreversatility in the overall design and construction of the housing 1920and/or the MCD 1900. For example, the ferrous tabs 1912 may besubstantially hidden (or “invisible”) when viewed from the outside ofthe housing 1920. Furthermore, the surface of the housing 1920 may beconstructed to be substantially uniform and/or flush with an outerfaçade of the MCD 1900.

Additionally, configuring the magnets 2012 such that their innermagnetic poles are all of the same polarity results in a lower DCmagnetic flux through the center of the device. For example, if themagnets 2012 were arranged such that the inner magnetic poles haveopposite polarities (e.g., one with north facing up and the other withsouth facing up), then a magnetic field would be created across thecenter of the dock 2000, from one of the magnets 2012 to the other. Asdescribed above, the magnetic flux through the center of the devicecould have an adverse effect on other circuitry within in the dock 2000and/or the MCD 1900. Thus, the arrangement of magnets 2012, in thecurrent embodiment, provide for more robust communications within (andbetween) the dock 2000 and/or the MCD 1900.

In alternative embodiments, the horseshoe magnet assemblies (or actualhorseshoe magnets) may be implemented on both the dock 2000 and the theMCD 1900 (e.g., in lieu of ferrous tabs). In addition to the advantagesalready described above, with respect to FIG. 36, such embodimentsprovide for a much stronger magnetic coupling between the dock 2000 andthe MCD 1900. Accordingly, this allows the corresponding magnets in thedock 2000 and the MCD 1900 to be set even further apart (i.e., furtherfrom the surfaces of their respective housings) while continuing tomaintain a relatively strong magnetic association with one another.

As still another addition or alternative such as shown with FIG. 34, thereceiving surface 2010 may be contoured inward. The back face 1915 ofthe MCD 1900 may include ferrous tabs 2912 that align with horse-shoemagnets. The result may include a magnetic coupling such as describedwith any of the embodiments provided herein.

Sticky-Back Accessory Device

While numerous embodiments described above provide for the dock to serveas a base for the MCD, FIG. 37 illustrates an embodiment in which theMCD 1900 may couple to a sticky-back accessory device 3000. In animplementation shown, magnetic cups 3050 may contain magnets 3020 on ornear a mating surface of the accessory device 3000. For example, themagnets 3020 may correspond to horseshoe magnet assemblies (or actualhorseshoe magnets), as described in any of the above embodiments. Aswith other embodiments, tabs 1910 may be provided on the façade (e.g.,housing 1920) of the MCD 1900. Such a device may magnetically clamp tothe back side of the MCD 1900 and thus function as a portable accessoryfor use with the MCD 1900. Functionality and features described with anyof the embodiments above may apply to the construction and use of theaccessory device 3000.

Additions and Alternatives

Numerous embodiments described above depict a docking station that isrested on a table-top or ground. However, embodiments furthercontemplate that a docking station in accordance with one or moreembodiments may be structured to mount to vertical environments, such aswalls or windshields of automobiles. According to an embodiment, adocking station or accessory device may include suction cups or similarstructures to enable the docking station to retain to the verticalsurface. In order to receive and retain a mobile computing device, oneor more embodiments provide that the accessory device includes magnets,such as described in sections provided above, to magnetically attract toferrous or like material in the mobile computing device. In such anembodiment, the mobile computing device may occupy anyone of manypossible orientations, and remain docked through use of relativelystrong magnetic forces.

While the magnetic clasping mechanism in the embodiments above have beendescribed with reference to permanent magnets, alternative embodimentscontemplate the use of electromagnets. For example, electromagnets maybe manually turned on and off to enable magnetic clasping between thedock and the MCD only when desired. This may help prevent undesiredferrous/metallic material from being attracted to the dock and/or MCD atrandom times. Additionally, turning off the electromagnets may also helpreduce magnetic interference with circuitry in either the dock and/orthe MCD while in an uncoupled state.

In a further embodiment, proximity sensors may be provided in the MCDand/or the dock to detect a proximity (or nearness) of the MCD to thedock. For example, the proximity sensors may be configured toautomatically (or programmatically) activate the electromagnets in thedock and/or MCD only upon determining that the housing surface of theMCD is within a specified range of the receiving surface of the dock.

While reference is made in numerous embodiments described herein todocking stations, other devices may be used to couple or mate with anmobile computing device in accordance with any of the embodimentsdescribed herein. For example, modules that carry functionality forenabling keyboard or inputs, cameras or image capturing (e.g. video),GPS, or modems may be provided in housings that can be coupled to theMCD via a sticky-back configuration, such as shown in FIG. 35. Suchembodiments may use magnetic clasping to hold the two devices together.As an alternative or addition, such embodiments may use signalconduction (e.g. see FIG. 1), inductive signal transfer (power or data)and/or orientation detection in a manner described above.
